  1. Geodized crinoid possibly.

    I believe these are geodized crinoid. Found at my residence in Casey county, Kentucky. I know crinoid are very common and I believe these could all be. I posted on here a month or two ago and have learned a bit since then but I like extra opinions. Thank you
  2. Trilobite geode

    Trilobide geode, bought in Morocco from a street vendor. I tend to assume it's real, because nobody would wish to work on a fake for such little money - but I will accept your expert judgement. Size about 6x4cm. If real, what is it?
  3. East Ks Geodes

    Hey all, I’ve found a number of these pretty geodized shells with incredible smoky and clear quartz crystals in the Kansas City area. Have you guys ever found anything like these?
  4. A fossil hunt for. . . geodes?

    Sometimes, when you go on a fossil hunt, you find more than just fossils. Some friends and I traveled to southeastern Iowa in Spring '18 to scour the Mississippian for fossils, but while there, we noticed that many of the homes that we drove by sported geodes in their front yards. Intrigued, we decided to investigate for ourselves. As it turns out, the area is well-known for its geodes (Iowa's state rock is the geode), so we promptly decided that we had to collect some for ourselves. We eventually found a privately owned piece of property where we could fill a bucket with geodes for about $20, descended upon a stream cutting into the bedrock, and filled a bucket in short order. Then, on a return trip to Iowa a month later, we found another outcrop of geodes along the Mississippi River. Once again, we collected handfuls. Then, once we got back, we split them with a geode cracker. They varied in quality; some were stunningly beautiful, and others were less so. They were filled with all manner of minerals: some had chalcedony fillings; others had quartz crystals, and still others had minerals that I didn't recognize. The colors varied, too: pink, white, light blue, red, and brown. As it turns out, we were a little overzealous in our efforts; we collected about 50 pounds of rocks. We've given them away to as many friends would like them and have only just now run out of them a year later. Pictured below is a fraction of the haul. If you happen to find yourself in this neck of the woods, then remember: the Osagean of Iowa and Illinois has more than just crinoids. If you would like more information on them, where you can hunt for them, or even the annual Geode Fest, then check out this link. http://keokukiowatourism.org/geodes/index.php
  5. I found this 'geodized snail' in a 25lb lot of kentucky geodes I got off of online years ago. I'm going to call it a geodized snail till one of you corrects me because thats how the seller referred to it in the post. Again, I haven't really prepped a fossil up to this point but I've gathered some information from this forum! From what I've gathered an airscribe would be a good way to start? Would it be safe to attempt to chisel off the larger chunk of matrix?
  6. This was from my Grandpa’s collection of ocean treasures. I think it is some sort of fossilized coral conglomeration, as I also see what looks like bits of shell. It weighs about two pounds. It also looks like a geode, but I always thought geodes were from the earth, not the sea. Any help you can give me would be appreciated!
  7. help, what is this urchin, egg, geode?

  8. My brother found this while hiking I believe around Mammoth Lakes, California. Its almost perfectly round and feels somewhat light so it may be hollow. Google says its a concretion. My mom thinks its a Geode. What do you think?
  9. Geode or marine fossil or....?

    This is the part I found, I know that I know the outside of this geode or rock or whatever from some thing, but I can’t find it... marine fossils....? Didn’t know if corals could be geodes if it is a coral, by all my posts on here everybody knows I don’t know what I’m doing
  10. Crystal Crinoid calyx?

    Hello all, I've come across something intriguing. A couple months back I found what looked like a geode. I've only recently got to splitting it, and got more than I bargained for I believe. This popped out of the dead center of the rock. I've given some of the other crystal lined peices to my brother, so I don't have all the peices of the outer. There are some brach bits in the rock, so there are fossil remains forsure. Are my eyes playing pareidolia on me, or does anyone else see what resembles to be a crinoid calyx? I'm happy alone to have the little brachiopodic bits druzied. All opinions are happily welcomed.
  11. Found these all laying around the same area by an old creek flowing from the mountains into the Yukon River, Alaska! it was like a nest of them! Lots of round rocks near this creek as well, then angles bedrock surrounding this creek area...the rounder ones are very heavy! Working on better pictures with a scale, weight, etc for identification.... in the upper left hand corner by the hand, the larger dark rock has 'rib' markings as well as the rock below it...then the small rock in the left upper corner by the hand seems to be fossilized bone or tusk... then the smallest round rock in the upper right corner is a smaller version of the larger.... the cross section of the broken one seems to have an outer shell of 1/4" thick shell, BUT..... and there are mineralized deposits on the outside as well as in the cracks of a couple of these...the 'broken' rock in the bottom left is a good example of the mineralization (I'm a sped teacher!, so don't take me to task for my lack of knowledge and terms!) BUT, these will look cool in my sauna!!!! The heavy ones are like cannon balls!
  12. Fossil geodes

    I found these super cool fossils turned geode today. Any idea what kind of crystals they might be? I was thinking calcite or quartz. Much appreciated. (Edit: Doesn’t react to vinegar, so silica or clear quartz maybe?)
  13. Is this petrified coral?

    I have about a hundred pounds of what I believe to be fossilized coral and sea plants. Any help would be appreciated.
  14. Any input would be great! I’ve had this lil thing on my desks since middle school after finding it on a beach in...possibly Michigan...on a vacation. Flipped over it has an appearance similar to a geode with clear crystal-like features.
  15. Fossil ID

    Hi everyone, On one of our family trips to Dickinson, ND a friend took us out into the Badlands about 30 years ago. We found this item and at a local fossil show the 4 choices were geode which I don't think is correct. Concretion or reptile egg were the other choices. I will attach a second photo in a minute. Thanks for any help you can give us.
  16. Geode with fossil

    Hello I just joined so first I will say hello my name is Julien I love in Colorado. I just acquired a new geode with a fossil iside of it. I was wondering if someone could identify what kind of geode it is and how rare it is to have one whole like this? Thank everyone for their help in advance I’m sure the members of this site are pretty smart.
  17. I peer into a small geode at 80x to look at what look like small blooms of crystals covering bulbous blue crystal mounds. Originally I wanted to see why the geode had white crystal patches on one side and the top side had darker spots. First I see that the "blooms" are actually super small stones that look to be growing their own crystals. I had to look further, I wasn't sure if the geode was opened when I chipped it free from the breccia or if had been open while it was encased. The crystallization was perfectly clean, so I surmise it was. Either way, how in the world does a geode crystallize and then later adopt a speckling of microscopic stones? So, I'm looking over the surface and there is this anomaly. does not match any of the features inside the geode. I look closer and it appears to have, internal organs, segmented legs, and antennae. Could this really be some type of shrimp? Or similar crustacean? I'm really curious to hear what you all think. Hopefully the images suffice, I have a biological microscope so it is not the best at 3D. Posterior Head/Antennae I know I've been looking at a screen all day, but this sure looks like a segmented/armored leg. And, I'm spent
  18. Help a 5th grader

    One of my students found this near Jacobia Texas and would like it identified if possible. I have more pictures of it on the forum's Facebook page.
  19. Geode?

    The fossil I want most to find, at this point in my addiction, is a tullymonster. A few months ago, I thought this might be one, but, now, I'm fairly certain it's just a geode and am just double checking by asking for an ID. I actually really dig (that's so punny, lol!) geodes, so I'll add it to my collection, but I have enough criniods and brachiopods. I'm throwing a little tullymonster fit!
  20. Crystal agate fossil?

    I found this today on the beach under a clay cliff, it is known for agate And chalcedony to be found on this beach, what would I call this, it looks like some sort of a bone maybe?
  21. Fish in Rock like a Geode

    Sorry, another fossil from my dead acquaintance's estate. This is an interesting fish in a geode-like rock. Open it up and you can see the top and the bottom of the fish's image. The person who split open the rock did an excellent job. The seam is sharp and tight. To get to the fish inside: It is about 10½ millimeters centimeters long and 4¾ mm wide/tall at its widest point. I did just a little bit of magic in this picture to heighten the image. I made it a little bit darker and heightened contrast just a little. The rock from the outside looks like a sweet potato. In fact, the inside of the rock has a reddish, sweet-potato coloring though where the ghost image of the fish is, it is grayish brown. I don't know where this fish was found. A nice fish, well-preserved by my eye.
  22. Fossil or Rock?

    I found this and several smaller ones in an ancient creek in the country of Georgia recently. This item is very heavy for its size. Can't figure out what it is.Please help.
  23. Okay What is It? Geode or Fossil

    Greetings once more, This is my second posting and has a direct correlation to my opening post. As previously stated the fossil/geode, displayed in the photos, has been in my possession since my father's passing in 2004. I have no idea as to where or how he obtained but will say that he was a traveler and collector of various items from around the world. The identity of this item has been the topic of many discussions between my wife and kids (now grown). They both still ask me as to "What is it?". So I humbly call upon the members today; What is it? FYI, I will be posting several high resolution pics (11) for your review Regards Mark
  24. Petrified wood and geode help!!

    Can anyone shed some light on these two specimens. I was given these from my technician last week. They were the possessions of her grandfather, who passed away last month. I told her TFF might be able to provide some info. Thanks for looking. Mike
  25. Folded Fish in geode

    Hello Fossil Fans, I found this fossil at a flea market in Paris this week. The seller said he'd gotten it from a collector who told him it was from Brazil and between 270 and 300 million years old. To me, it looks like the fish is curled up in a ball, or folded. What do you see? Any info would be great! Thanks.
